Considering the molecular orbital theory (MOT), chooses the correct relative energies order.
Correct answer: A. σ1s<σ*1s< σ2s< σ* 2s< σ2px< π2py = π2pz
- A. σ1s<σ*1s< σ2s< σ* 2s< σ2px< π2py = π2pz
- B. σ1s<σ*1s< σ2s<σ*2s< π2py = π2pz<π2px
- C. σ1s<σ*1s< σ2s<σ*2s< π2px = π2pz< π2py
- D. σ1s<σ*1s< σ2s<σ*2s< π2py< π2pz< π2px

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
